For runners
Stop training off your watch's guess.
Your GPS watch estimates VO2 Max from an algorithm. Our treadmill test measures it directly, breath by breath, so your training zones, including true Zone 2, are built from your actual physiology.
Find your true Zone 2
Most endurance adaptation happens in Zone 2, but a mis-estimated max heart rate throws off every zone built on top of it. We measure yours directly.
Reprogram your GPS watch
Once you have your real max HR and anaerobic threshold, you can update your watch's zones so every training run reflects your actual physiology.
Pair with RMR for race fueling
Add an RMR test to know your true daily caloric burn, useful for dialing in fueling during marathon or ultra training blocks.
Run on real data
Bundle VO2 Max with DEXA and RMR and save $30 versus booking each separately.
